Common Reasons Why Trench Drains Get Clogged

Common Reasons Why Trench Drains Get Clogged

The trench drain, also known as a channel drain, is a specialized drainage system that can manage surface water runoff in various situations. Trench drains are normally constructed of fiberglass, polymer concrete, or concrete and laid level with the ground. They resemble narrow troughs or channels.

The main purpose of trench drains is to collect water and divert it away from potential trouble spots such as industrial facilities, parking lots, driveways, and patios. By efficiently diverting water to specific drainage points, trench drains help prevent flooding and erosion, making them especially useful in regions with heavy rainfall.

Trench drains are available in a wide range of designs and sizes to meet the demands of diverse loads and flow rates. They may have covers or grates that let water in while keeping debris out of the drainage canal. Certain trench drains have built-in features that remove impurities, such as oil separators and sediment traps, to improve water quality.

There are several potential causes of clogged trench drains, including:

  • Building debris:

While construction and upgrades are underway, debris like gravel, sand, or cement can clog the trench drain.

  • Freezing and thawing

Water in trench drains has the potential to freeze and clog in winter in regions with lower average temperatures. Thawing may further dislodge debris, thereby exacerbating the problem.

  • Sedimentation

The trench drain’s capacity decreases, and blockages become more likely as time passes and sediment settles into it.

  • Rust and corrosion

Rust and corrosion in the drain system can cause clogs and reduce water flow.

  • Oil and grease

Grease and oil can build up in trench drains in commercial and industrial environments, particularly in garages and parking lots.

  • Litter and garbage

Trench drains are prone to blockage with trash such as wrappers, plastic bags, litter, etc.

  • Poor maintenance:

When people don’t regularly clean and maintain trench drains, obstructions can build up over time.

  • Plant growth

When plants in the area send their roots into trench drains, it can clog them and even damage the drainage system.

  • Insufficient design or installation

Clogs in trench drains can occur due to poor design or installation, such as the wrong size or inadequate slope.

  • Accumulation of debris

Debris collection, including rocks, dirt, leaves, and other items transported by water flow, is a typical cause of blockage.

The importance of unclogging trench drains

Preventing Structural Damage

Damage to pavements, walls, and foundations can occur when standing water seeps into nearby structures due to clogged drains. Unclogging drains is necessary to prolong infrastructure life and avoid water damage.

Maintaining Infrastructure

Regular unclogging of trench drains keeps them in good working order. Regular debris removal could lead to costly replacements or repairs for a clogged drain system.

Compliance with Regulations

To prevent environmental pollution and flooding, many towns have passed legislation mandating that property owners maintain drainage systems, which may include trench drains. Regular unclogging ensures compliance with these rules.

Safety Concerns

Clogged trench drains pose a safety concern, particularly in heavily populated regions. Wet, slippery surfaces increase the likelihood of accidents. Minimizing such threats by keeping drains free promotes safety for pedestrians and drivers.

Prevent Pollution 

Trench drains gather more than rainwater; contaminants, sediment, and debris are common. Unclogging them helps keep these pollutants out of waterways, which is good for ecology and water quality.

Flood Prevention

The drains redirect water away from high-risk locations to prevent flooding. However, clogged drains can cause safety hazards, property damage, and flooding concerns due to water pooling.

The importance of an outlet for a trench drain

The outlet of a trench drain significantly influences its efficiency and functionality. Here’s why it is essential:

Common Reasons Why Trench Drains Get Clogged

  • Aesthetic Considerations

Aesthetically sensitive regions, such as residential landscapes, commercial properties, and public places, are prime locations for trench drain installations. Installing an outlet that drains water effectively without leaving standing water or pools will increase a space’s aesthetic value.

  • Maintaining Safety

Good drainage is crucial for keeping things safe, particularly in places where there are water pools. Properly functioning outlets quickly remove water, reducing the likelihood of slips and falls. Proper drainage also aids in avoiding the accumulation of potentially dangerous materials in industrial environments.

  • Blockage Prevention 

Typically, we install a filter or grate system at the outlet to prevent material from entering the drainage system. This prevents clogs that could cut off water flow. A drain with a clear outlet will last longer between cleanings and require less overall maintenance.

  • Infrastructure Preservation

Without proper drainage, water can gradually erode infrastructure. Excessive dampness can cause soil erosion, foundation weakening, and structural compromise in buildings and pavements. The outlet helps to preserve adjacent infrastructure by providing a clear pathway for water to exit.

  • Water Drainage

A trench drain’s main goal is to efficiently remove water from a specific region. The collected water leaves the drain system via the outlet. If the outlet isn’t working properly, water could pool and cause damage, erosion, or flooding.

Improving aesthetics, safety, clog prevention, and infrastructure preservation is crucial for efficient water drainage. If you want your trench drain system to work properly, you must ensure the outlet is well-designed, installed, and maintained.

Do trench drains need a trap?

Trench drains typically lack the conventional water traps found in standard shower or sink drains due to their large water flow capacity and frequent installation in outdoor or industrial environments, where the containment of unpleasant odors is not a concern. Nevertheless, traps and sediment are not interchangeable; the latter two are ideal in certain trench drains to collect material and avoid blockages. The design and intended use of a trench drain determine the need for a sediment basket or trap.

Does a trench drain need an outlet?

Yes, an outlet is usually necessary for a trench drain to work properly. To avoid floods and water damage, a trench drain collects surface water and reroutes it away from an area. If there were no way to release the collected water, it would only pool inside, rendering this feature useless. When a drain has an outlet, water can leave and go to a storm drain, sewer, or other suitable drainage system.

Conclusion

Unclogging trench drains is essential for preserving water quality, preventing floods, ensuring safety, and maintaining infrastructure integrity. In addition to protecting properties and the environment, regular maintenance and quick unclogging can save time and money in the long run.
